The lengths he'll go to to uncover the tooth

For millions of years, much of Florida, including Venice, was under water and prime territory for millions of prehistoric sharks.

Sharks shed as many 35,000 teeth in their lifetimes, leaving billions of teeth that sank to the ocean floor, where they became embedded in minerals and fossilized.

Geological changes, including a jutting land mass that ran from Venice more than 150 miles into the Gulf of Mexico, released the teeth.

While renourishment of Venice Beach has made shark teeth less plentiful, they are abundant offshore. Divers from around the world search what is dubbed "The Venice Boneyard" a mile or so offshore for prized shark teeth and other fossils.

Among the most prized finds are Megalodon teeth, as large as 6 inches, from prehistoric sharks that were 90 feet long.
